Why does Amazon create a unified account in several countries by default ?

All right, I am new to selling on Amazon, and I am running into an unforeseen difficulty.

When I create a seller account from my national (French) Amazon website, the application creates by default a united account with stores in several random countries.

In my first try, I had accounts in 10 European countries plus the United Arab Emirates. In my second try, I had stores in all of North America plus 2 or 3 random countries, but not France. Now for my 3rd try I have France plus USA, Singapore, and I dont remember what other countries.

The support explained to me on 2 disctinct occasions that it was not possible to close an account in a specific country from a unified account : you can only 1) put in “vacancy mode” the countries you are not using or 2) delete your whole unified account.

Did someone run into such trouble ? Do you know a solution so that Amazon does not create a random unified account by default ? I don’t want to have stores and pay subscriptions in numerous countries that are of no use to me. Thanks
